Facts:

A resigned from his full time job as a cashier to operate a farming business.

A contracted with B to install a sprinkler system for his farm to grow potatoes to control a moisture level of 30% (contract price $1000)

A agreed to a partnership with C for the potato business. However, C was not fond of A as he was a direct competitor of his and wanted to ruin A's business therefore agreed to the partnership.

C subsequently sold faulty seedling plants so that A will not be able to fulfill his contracts to his suppliers, in which he was about to earn $3000 a month for.

It was also found that the sprinklers were incorrectly calibrated and the moisture level was set to 3% therefore the soil dried up and the potatoes died. A also then realised that the seeds he bought from C were faulty.
